在无线传感信号传播中，如何对信号进行采样，避免因强杂波干扰和无线传感信号频谱的重叠而产生的混叠失真干扰，导致信号处理分析结果出现错误，一直是信号处理上的难题。提出一种引入等差恢复概念的无线传感信号处理方法，利用差分信号抗干扰的特性，对已经失真的无线传感信号进行差分数字化处理，在被破坏的无线传感信号恢复过程中，对设定点的无线传感信号进行中心差分处理，差分后的信号可以很好的保证抗干扰特性，恢复后的信号与设定点再差分，实现传感信号恢复。通过仿真实验，与其它方法进行比较，从实验结果可以看出等差恢复法能更好地体现无线传感信号的真实性。

In the wireless signal transmitting, it is a difficult problem to deal with signals, how to sample continuous signal, to avoid spectral overlap interference causing aliasing distortion, error analysis resulting in signal processing analysis. Arithmetic restoration concept is advanced to deal with wireless sensor signal , using differential signal anti-interference characteristics, doing difference digital to distorted wireless sensor signal ,In the process of Restoration to destructed wire?less sensor signal, makes central difference to set-point wireless sensor signal , Differential signal can well ensure anti-in?terference characteristics, sensor signal recovered by making difference between the restored of signals and set point differ?ence sensing signal .Through the simulation, Compared with other methods ,it can be seen from the experimental results that Arithmetic restoration method can better reflect the authenticity of the wireless sensor signal.
